Re: [Sheflug] Drive detection

Ian,

I'd wait for the experts to correct me on this one, but I think you're
making this far too complicated for yourself. You've got the standard
4 ide devices set up as follows:

/dev/hda	 Hardisk	1st IDE bus Primary
/dev/hdb	 CDROM		1st IDE bus Slave
/dev/hdc	 Hardisk	2nd IDE bus Primary
/dev/hdd	 CDROM		2nd IDE bus Slave

You currently have a symlink /dev/cdrom pointing at /dev/hdb 

It's just a symlink, not anything magical so that software has an easy
way of finding the cdrom drive. So if you want to use the other drive
as the primary cd player, change the symlink, so that it points to the
new drive. 

So as far as fstab is concerned, try something like this.
change /dev/cdrom so that it points at the main drive
create /dev/cdrom1 so that is points at the other drive.
(by create I mean:"ln -s /dev/hdd /dev/cdrom1"

in fstab you should have something like this, but remember it's all
one line, not line wrapped like in this email

this line covers the main CDROM drive

/dev/cdrom      /cdrom          iso9660
defaults,ro,user,noauto         0       0

for the other drive 

/dev/cdrom1      /cdrom1          iso9660
defaults,ro,user,noauto         0       0

make any sense?

Simon
